HEADER.

SPECIFICATION forming part of Letters Patent No, 285,720, datedSeptember 25, 1883.

' Application filed April 3, 1883. (No model.)

To all whom it may, concern:

Be it known that I, JAMEs H. Warn, of Benicia, county of Solano, Stateof California, have invented an Improvement in Headers; and I herebydeclare the following to be afull, clear, and exact description thereof.

My invention relates to certain new and useful improvements in thatclass of agricultural implements known as headers.

My invention consists in the peculiar arrangement of acompensating-spring,eccentric, pulley-chain, and beam, as will behereinafter particularly described, and specifically pointed out in theclaims.

Referring to the accompanying drawing, the figure is a perspective viewof the rear of a header showing my improvements, the wheels being leftoff and a portion of the beam B being broken away.

A is a portion of the header.

Bis the beam, having a cross-head, b, which is hinged to the header inthe usual and wellknown manner.

G is the steering-wheel, and c the platform for the operator.

D is the lever, attached to the header at d and d. It extends back overthe beam, and is adapted to engage with a rack, E, extending upward. Itis by the movement of this lever that the front of the header is raisedor lowered.

The beam B, instead of being made of a single piece, is here made of twopieces suit-ably bolted and braced, leaving a slot, 1), between them. Inthis slot is the pulley F, pivoted to the beam eccentrically at f. Thispulley is shown as a sprocket-wheelto adapt it to engage with the linksof the chain G, the upper end of which is connected with the lever D.

H is a strong spiral spring under the beam. One end of this spring issecured to a bolt, 71, which passes through a stationary bearing-lug, h,under the beam, and takes a nut, h", whereby the tension of the springmay be regulated. The other end of the spring is secured to the end ofchain G. r

The operation of the device is as follows: When the lever D isdisengaged from its rack, the spring assists in lowering it to raise thefront of the header. In lowering the front the tendency of the header togo down is resisted by the spring, and the stronger the tendency thegreater the resisting power of the spring in being drawn out. Thisresistance is augmented by the eccentric F, in that it requires lessmovement of the lever, when it is near its highest position, to draw outthe spring a certain distance than when said lever is near its lowestposition. If the pulley were centrally pivot ed, the distance throughwhich the spring would be drawn out would be the same in all positionsof the lever. It therefore enables me to use a shorter and strongerspring, whereby the device can be attached in a neat manner and be outof the way.

With this spring as a counter-balance the lever may be moved up or downwith the exas I here show, it is stronger, lighter, and

less liable to warp; and a further advantage is gainednamely, that itfurnishes by its central slot a secure and neat bearing for theeccentric, which may be entirely or partially inclosed, though it mightalso be mounted to one side of the beam, if deemed preferable.

I do not claim, broadly, the employment of a spring to accomplish theresults herein set forth, but simply my construction and arrangement asshown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A header, and its hinged beam, in C0l11- JAMES H. XVINN.
